Continuity: When Daniel Stern's character takes Capt. Bosch down to the sewer area for the first time, the sweat, oil and dirt stains on his tank-top change constantly. The is most noticeable when they first descend into the cellar, where the shirt looks almost perfectly clean after being extremely dirty just a split second before as they start to climb down. Also, a little later, there's all of the sudden an enormous sweat stain on his chest that disappears later.
